An optical device includes a substrate, an electronic component and a lid. The electronic component is disposed on the substrate. The lid is disposed on the substrate. The lid has a first cavity over the electronic component and a second cavity over the first cavity. The sidewall of the second cavity is inclined.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The optical device of claim 1, further comprising a light filter disposed within the second cavity and the adhesive material is disposed between the light filter and a sidewall of the second cavity.
3. The optical device of claim 1, wherein a projection area of the support structure on the substrate and a projection area of the adhesive material on the substrate are non-overlapped with each other.
4. The optical device of claim 3, wherein the adhesive material has a substantially triangular shape from a cross-sectional view.
5. The optical device of claim 2, wherein a projection area of the light filter on the substrate and a projection area of the adhesive material on the substrate are non-overlapping.
6. The optical device of claim 5, wherein a lower surface of the light filter facing the support structure is exposed from the adhesive material.
7. The optical device of claim 6, wherein the support structure is disposed adjacent to at least one of corners of the first cavity without extending along an edge connecting two adjacent corners of the first cavity.
8. The optical device of claim 7, wherein an edge of the lower surface of the light filter is exposed from the support structure.
9. The optical device of claim 8, wherein a projection area of the light filter on the substrate is entirely within a boundary of a projection area of the support structure on the substrate.
10. The optical device of claim 8, wherein the support structure has a top surface, and the bottom surface is opposite to the top surface, and a lateral surface extending between the top surface and the bottom surface, and wherein the lateral surface is substantially perpendicular with the bottom surface.
11. The optical device of claim 10, wherein the support structure has a portion in contact with the light filter, and the portion of the support structure has a substantially constant thickness in a cross-sectional view.
13. The optical device of claim 12, wherein the support structure has a substantially triangular shape in a top view.
14. The optical device of claim 12, wherein the support structure has a lower surface facing the substrate and an upper surface opposite to the lower surface, and wherein the upper surface is substantially parallel to the lower surface.
15. The optical device of claim 14, wherein the support structure further has a lateral surface extending between the lower surface and the upper surface, and wherein the lateral surface is substantially perpendicular to the lower surface.
16. The optical device of claim 15, wherein the upper surface, the lower surface, and a surface of the substrate on which the electronic component is disposed are substantially parallel.
17. The optical device of claim 15, wherein the support structure has a substantially constant thickness in a cross-sectional view.
